Not a DVD at all. It's from a TV show called DiscTV, a short-lived (2002) television program that ran on mostly obscure cable channels here and there. It was produced and hosted by a guy by the name of Brian Sullivan (he's the play-by-play voice in that linked video).
He traveled around to various tournaments to cover them and produce a weekly one-hour show with highlights. Usually, the coverage consisted of a Final 9 or a final round in the case of USDGC. He'd often grab a player who didn't make the final for live commentary (sorta what Terry Miller does now).
The old web site no longer exists, but you can find it at the Internet Archive (

Yeah, that's right, there was once a disc golf TV show before there was ever a Disc Golf Planet or any of the Youtube channels. It was well ahead of its time.
